We measure an unambiguous fundamental period of 6.2562 +/- 0.002 d, within 0.02% of half the orbital period (Porb = 12.50995 +/- 0.00036 d) determined earlier from HST observations resolving the binary. The light curve is double-peaked, and well fit by the sum of two sinusoids: a primary with period Porb/2 and peak-to-peak amplitude 0.120 +/- 0.012 mag and a secondary with period Porb and peak-to-peak amplitude 0.044 +/- 0.010 mag.
